Y corners'of a square to receive theY inner coils 8b Referring to the drawings, foci-tain portions of of the springs `8 about the same and assist in .acar truck are: illustrated, which include a side centering the various springs. Projectingdown- 55 Wardly from the central portion of the under surface of the roller seat is a rib 15 which, in the embodiment shown, is of substantially squareshape and this rib racting in conjunction with the flange 13 serves to center and prevent displacement of the upper ends of the outer coils 8a of the springs4r 8. VIt should perhaps be here stated that spring centering cylinders 14 Vof a requisite number to accommodate any desired number of VspringsV in a spring group may be provided on the under surfaceof the roller seat and that suitably formed ribs correspondingin function to the rib 15 may be provided on the under surface of the roller seat to act with the cylinders and with the flange 13 to house and prevent displacement of the upper ends of thesprings 8. It should also be stated that it is not essential that springs 8 including both inner"y and outer Ycoils 8a and 8b be used with the roller seat inasmuch as the inner coils may be eliminated entirely, theV outer coils may be eliminated entirely or, if desired, the vspring group may include certain springs having only inner coils, certain springs having only outer coils, or the spring group mayinclude certaincompoun'd springs and certain springs having only outer coils.

On the upper surface of the roller seat, there are formed preferably a plurality of spaced parallel roller beds 16 which project upwardly somewhat from the remainder of the upper surface of the Vseat and lextend generally longitudinally thereof. 'I'hese roller beds are preferably of Y concave curvature as shown and the rollers 10 are received partially within the same to work thereover. ,These roller beds are notched inwardly at theirsides to form notched portions 1'7 at the inner side of the innermost bed and at the outer side of the outermost bed and to form depressions 18 vor notched portions set between adjacent beds at lower levelsv than the beds. Drainage openings y' 19are provided through the roller seat and these openings extend fromthe depressedportions 18 through opposite corners ofthe rib 15 in such position that Water draining through these openings will fall betwen adjacent springs 8.

The corners of the various roller beds 16 are also notched by notches 20 and 21 to form passages through which dirt and dust may be swept by wind action and also by travelof the rollers 10 onv the beds 16. lUpstanding lugs 22 are pro'- vided at the unnotched portions of the side edges of the roller beds and these lugsv limit rolling movement of the rollers transversely of theV beds and roller seat. Certain of these lugs 22 placed between adjacent beds 16 connect the adjacent beds and serve as outer stops Hunting outward rolling action of the rollers in certain beds and the inner rollingaction of the rollers in `beds adjacent thereto. At the unnotched portions of theends of the beds, upstanding lugs 23 are provided which limit endwisejmovement of the rollers 10 longitudinallyrof 'the'beds It should be noted that the notches 20 and-21 space the lugs 22 both longitudinally and'transversely vof the roller seat from the lugs v23 adjacent thereto.

When one of the roller seats A is in use on a car truck, the springs 8 of the spring group bear directly against the underside of the roller seat and lthe upper vends of these springs are housed and centered by the iiange V13, the cylinders 14` and the rib 15. 'Ihe rollers 10 are, of course, free for travel in the roller beds 16 and as the rollers travel back and forth through lateral motion of the bolster 9 relative to the side .of the notches in these beds.

frames 5, the rollers will work any dirt or dust f portions 18 may take place through the drainage openings 19 and drainage of vvater from the roller beds 16 may take place readily by reason As Water will not accumulate in the depressed portions'18, the roller beds will dry out much faster than would otherwisefbe the case if the Adrainage openings 19VV were not provided and, as a result, dust or dirt caught by the Water and tending to'acciunulate in the roller beds may beV swept by the windV and acted on by the rollers to clear the roller beds much quicker'than wouldV be' the case if the drainage openings 19 were not provided. The rib l5 in addition to acting to center the springs 8 also serves to strengthen the roller seat.

It will, of course, bevunderstood that various changes may be made in the roller seat to adapt it for use with other types of Vspring groups than the type illustrated. -It will be'vfurther-funder-r vided in the roller seat. Itwill also be under'- stood that various other changesmay be made in the form, details, arrangementand'propor'- tions of the various parts without departure Vfrom the scope of the present invention. f
